This is an Ithaca Model 37 shotgun, as manufactured in 1974, with trench handguard attachment and "USSF" stamped on the lower left of the receiver. A nearly identical Ithaca Model 37 trench gun is illustrated on page 267 of "The Worlds Fighting Shotguns" by Thomas F. Swearengen with the caption, "Right side of an Ithaca Model 37 reportedly made for Army Special Forces." The barrel is fitted with a six-hole heat shield with bayonet adapter stamped "SP-30-06" on the right. The left side of the barrel is roll-stamped with the two-line Ithaca legend followed by "CYL". The Ithaca "Roto-Forged" logos are stamped on the right of the barrel and receiver. The pistol grip stock has impressed checkering on either side of the wrist, and is fitted with an Ithaca branded black plastic buttplate. Includes a brown leather M1907 sling and a "1918" dated Springfield M1905 bayonet with olive drab green scabbard.

Excellent plus, retains 98% plus original parkerized finish with light cycling wear visible on the magazine tube, and sharp markings and edges in the metal. The wood is also excellent with some light handling marks, a few small nicks on the bottom of the buttstock, and distinct edges and checkering. Mechanically excellent.
